Description

The invention relates to a lamp element and a lamp, in particular a room lamp, for uniform and / or variable illumination of a room.

Numerous concepts for lighting a room are known from the prior art. As a rule, spotlights, LEDs or fluorescent tubes that are permanently installed in a luminaire are used as light sources. It is also known that an illumination color and / or a color temperature can be variably set. In general, the angle at which light is emitted by the lamp is limited by the geometry of the lamp, since operating devices and devices for accommodating the lamps cause shadows to form.

Proceeding from this prior art, the present invention is based on the object of providing a lighting element and a lighting fixture that enables uniform and / or variable illumination of a room by emitting light from the lighting fixture in all spatial directions.

This object is achieved according to the invention by a lighting element having the features of claim 1 and a lamp having the features of claim 12.

According to the invention, a luminaire element has a channel-like carrier, electrical and / or electronic components and / or one or more circuits and / or lines and / or operating devices as well as several lighting means.

The channel-like carrier is elongated and open towards an upper side and has a concave inner side in which the electrical and / or electronic components and / or circuits and / or lines and / or operating devices are arranged. It also has a convex outer side on which the lighting means are attached.

In other words, the lighting element is designed so that many or all of the electrical or electronic components required for operation are arranged in the concave interior of the channel-like carrier, while the lighting means are arranged on its outer sides. This enables light to be emitted around the carrier cross-section in all directions. Shadows from the components required for the operation and / or the attachment of the light sources are avoided at all angles.

In this context, a channel-like carrier can be understood to mean a component with walls, the interior space of which, bounded by the walls, is designed to accommodate the electrical and / or electronic components, circuits, lines and / or operating devices required for operating the lamp. The dimensions of the channel-like carrier can be selected so that the corresponding electrical and electronic systems can be accommodated therein. This includes cabling, switches, electronic control or driver systems, transformers, ballasts, starters and / or capacitors. In addition, a WIFI / WLAN module or another wireless module (Bluetooth, infrared, ...) can be provided that enables remote control of the lighting element, or a device for providing energy for emergency lighting for short-term power interruptions.

The channel-like carrier can be designed such that it has an elongated shape. Then the extension along the directions of a normal to the cross-sectional areas of the channel-like carrier is many times longer than the cross-sectional area is wide.

The end faces of the channel-like carrier in the longitudinal direction can be designed to be open, which enables lines to be continued out of the lighting element and / or the connection of electrical and electronic components, circuits, lines and / or operating devices with electrical and electronic systems located outside the lighting element.

The channel-like carrier can have an open side, viewed in the circumferential direction, so that the electrical and / or electronic components required for operation can be installed by simply placing them in the channel. The open side can, for example, in the case of a rectangular, polygonal or similarly shaped cross section of the channel-like carrier, be a completely open side of the cross section, or even just a gap which has a dimension of a few millimeters to centimeters. The open longitudinal side is preferably positioned on the upper side of the channel-like carrier so that the side and lower walls of the channel-like carrier hold the electrical and electronic components of the lamp in position and underpin them. Correspondingly, an upper side of the channel-like carrier is to be understood in particular as a side which, in an intended operating and assembly state of the light, is arranged against the effective direction of the weight force.

The inside of the channel-like carrier is concave. That can be understood as that a hollow interior space of the carrier is defined by the walls of the carrier. The cross-sectional shape of the carrier can be a curved line, but can also be limited in a straight line and have corners. In other words, the cross section of the carrier can be U-shaped or rounded, but can also have other cross-sectional geometries, for example V-shaped, W-shaped, trapezoidal, rectangular. Correspondingly, the convexly shaped outer side of the channel-like carrier can also have different cross-sectional geometries, which can be similar to or different from the inner side of the carrier.

The light sources can be LEDs or OLEDs, with several LEDs being able to be connected to form LED strips and several LED strips being able to be built into a lighting element. In addition or instead, incandescent lamps and / or fluorescent lamps, compact fluorescent lamps, low-voltage lamps, general-purpose incandescent lamps, high-pressure lamps, (movable) emitters, possibly lasers and other illuminants, can also be used. The multiple lighting means attached to the lighting element can be the same or different lighting means, in particular they can have the same or different light color and / or color temperature. The light color and / or color temperature of the illuminants can be set individually and the different illuminants can be activated, deactivated and controlled individually.

The channel-like carrier can have a first end and a second end and a straight or curvilinear course in between. The walls of the channel-like carrier can be closed surfaces or have more or less openings. They can be formed in one piece from a profile with a partially rounded and / or partially canted channel-like cross section or in several parts from a plurality of mounted support components.

The first end and the second end of the channel-like carrier are defined by the end faces in the longitudinal direction of the channel-like carrier, that is to say the outward cross-sectional areas of the channel-like carrier in the longitudinal direction. The appearance of the lighting element can be made variable by the course of the carrier between the first end and the second end, in that the lighting element is either straight or curvilinear. For example, a curvilinear lighting element in plan view can be a sector of a circular ring, have a wave-like shape or any other geometry.

In the end regions of a lighting element, viewed in the longitudinal direction, the longitudinal axis of the carrier can be perpendicular to the cross-sectional areas of the respective end of the carrier, or it can run at a different angle thereto.

The channel-like carrier can be produced in one piece in a particularly simple manner from a profile, for example with a U-shaped or other-shaped cross-section, and a rounded or elongated longitudinal course. According to a further embodiment, the channel-like carrier can be composed of several carrier components, for example several carrier plates. The carrier sheets can be made of 3 mm or 4 mm thick aluminum sheet or sheet of other thickness and / or of another material. In any case, openings of different geometry, dimensions and position can be made in the channel-like carrier, for example to ensure optimal removal of the waste heat from the electrical and / or electronic components during operation of the lamp and / or to save weight. For example, the carrier material can also be perforated plates with round, rectangular or otherwise shaped recesses, or wire mesh. In the case of a multi-part channel-like carrier, the carrier plates can advantageously be arranged in such a way that convection of heat-carrying air through gaps between the carrier plates is possible.

The lighting element can have a carrier element which is positioned along the open side - often the top - of the channel-like carrier and is vertically spaced from it. The distance between the top of the channel-like carrier and the carrier element can be determined depending on the application, but is advantageously chosen so that, on the one hand, effective convection of heat-carrying air is possible between the carrier element and the channel-like carrier and that, on the other hand, simple assembly, e.g. B. Insertion, the electrical and / or electronic components for operating the lamp in the channel-like carrier is possible. The distance can be over 5 or 10 or 20 or 30 mm. It can be less than 60 or 50 or 40 mm.

The carrier element can be a plate-shaped element, a carrier sheet made of solid material or perforated sheet material, a channel-like carrier element, or a rod-shaped carrier element. The carrier element can for example be formed from 4 mm thick aluminum sheet, also from 3 mm thick aluminum sheet and from sheet metal of a different thickness or of a different material. In particular, as long as an efficient removal of operational heat is guaranteed or as long as only a negligible operating heat is generated and as long as the assembly of the electrical and / or electronic components remains possible, the distance between the channel-like carrier and the carrier element can also be selected so small that an at least substantially closed channel is formed by the channel-like carrier and carrier element.

At least one further illuminant can be attached to the carrier element. The illuminant can be mounted on the outside with respect to the cross section of the channel-like carrier and the carrier element, so that the angular range in which light is emitted by the lamp is increased by the additional illuminant or that the illumination over the entire angular range in the circumferential direction the support structure becomes more uniform around. The further illuminant that is attached to the carrier element can be the same as or different from the plurality of illuminants that are attached to the channel-like carrier.

Electrical and / or electronic components, circuits, lines and / or operating devices, for example control electronics and / or power electronics or the like, can be attached to the carrier element on the inside with respect to the cross section of the channel-like carrier and the carrier element.

With regard to the cross section of the channel-like carrier, the lighting means can be arranged at several points in the circumferential direction around the channel-like carrier and optionally the carrier element in such a way that they emit their light away from the lamp element in different spatial directions. In the circumferential direction around the channel-like carrier and the carrier element, the entire angular range can be illuminated by the installed lighting means. A plurality of lighting means can be arranged in the longitudinal direction on the channel-like carrier and the carrier element in such a way that illumination takes place in different spatial areas along the entire length of the lamp element.

The lighting element can be installed with a lampshade, which can be made in one piece or in several pieces. It preferably has a material that scatters the light from the illuminants. The lampshade can more or less completely surround the lighting element when viewed in the circumferential direction. However, it can then also have gaps and / or openings that enable convection of heat-carrying air through the gaps and / or openings in order to ensure that the operating heat is transported away from the lamp. The lampshade can also be designed without such gaps and / or openings and have a completely closed shape. A multi-part lampshade can, for example, be composed of several plate-shaped elements which can be arranged in such a way that gaps remain between the plate-shaped elements. In addition, the lampshade can be designed in such a way that glare-free illumination of the room is achieved by scattering the light when it passes through the lampshade, for example using frosted glass or opal glass materials, surface structuring using microprisms or also through the use of paper or fabric materials. The shape of the lampshade can be adjusted as required.

The lighting element can have at least one holding element with a first fastening area, to which the channel-like carrier and / or the carrier element are fastened. The holding element can be plate-shaped and can be flat and attached to one end or to a longitudinal position of the channel-like carrier spaced apart from the ends. The holding element can be formed from a plurality of plate-shaped elements lying next to one another or one above the other and / or joined together, which brings with it an increased stability of the holding element. It can be built from stacked flat sheets of metal. Several holding elements can be fastened at different longitudinal positions of the channel-like carrier.

The first fastening area can, for example, comprise bores for fastening the channel-like carrier by means of screws and angles, or it can also have recesses which enable the channel-like carrier to be inserted into the holding element. Other designs, for example plug-in O the locking connections are conceivable. The carrier element can also be fastened to the holding element.

The holding element can moreover be configured or contribute to mounting or holding the lighting element as intended in a predetermined position, for example on or under a ceiling of a room. For this purpose, a recess as a fourth fastening area on the holding element can offer an attachment for a suspension. The suspension can take place by means of one or more steel cables, for example on a room ceiling. The introduction of a steel cable into the holding element can take place from the top. A supply conductor for operating the lighting element can also be introduced into the lighting element from the top. The holding element can likewise be designed to hold further components of the lighting element.

The lampshade can be attached to the holding element, preferably in a second one Attachment area. Like the first fastening area, the second fastening area can have different shapes in order to fasten the lampshade by plugging in, snapping into place, screwing or otherwise. It is conceivable that the lampshade is also fastened to the holding element via the first fastening area.

The holding element is preferably designed to connect the lighting element to at least one similar or different lighting element, preferably by means of a third fastening area. Like the first and the second fastening area, the third fastening area can have different shapes in order to establish a connection with a further lighting element. It is also conceivable that the first and / or second fastening area are used to establish the connection with a further lighting element. A screw connection to a further lighting element is preferably conceivable, as a result of which a high level of stability is achieved. A plug-in or latching connection or some other connection between the lamp elements and the holding element is also possible. If a holding element is flat, a first lamp element can be attached to one of its main sides as described. On its other main sides, a second lighting element can be attached, which can also be designed as described or differently.

Luminaire elements of different types can be either luminaire elements with a differently shaped channel-like carrier or luminaire elements with a fundamentally different structure, for example radiator elements that include one or more radiators that emit light in one or more directions. Their extent in the longitudinal direction of the lamp element described above can be comparatively short, length to width in plan view can be, for example, less than 2: 1 or can be between 1.3: 1 and 0.7 to 1. By connecting several luminaire elements by means of one or more retaining elements, variable luminaire geometries can be achieved.

A holding element can be attached to one end of the channel-like carrier and can have correspondingly profiled areas and / or recesses for receiving and / or connecting to the channel-like carrier, the carrier element, the lampshade and / or for the passage of the electrical and / or electronic components, Have circuits, lines and / or operating devices. Recesses in the holding elements, which enable the electrical and / or electronic components to be connected across multiple lighting elements, have the advantage that lighting constructions that include multiple lighting elements only have to be provided with as many electrical and / or electronic components as for the Operation of the luminaire. This means that not every luminaire element has to be equipped with a complete set of electrics and / or electronics. Some may only carry the light bulbs and wiring and possibly plug connections. At the same time, it is possible in this way to control selected lighting means that are attached to different lighting elements with a common control device, switch and / or dimmer.

The channel-like carrier and / or the carrier element and / or the holding element can comprise metal, in particular aluminum, and can be made exclusively from this material. The channel-like carrier, the carrier element and / or the holding element can be made entirely of aluminum. Due to the good thermal conductivity of metals compared to, for example, plastic materials, an efficient distribution and dissipation of the waste heat generated during operation of the lamp is achieved. In addition, a light element made of aluminum, for example from 3 mm or 4 mm thick aluminum sheet or aluminum sheet of a different thickness, has a high level of stability, which enables larger lights to be constructed from several light elements. A further increased stability can be achieved in that the holding elements are made in several parts from several aluminum plates, preferably, for example, from 5 plates each with, for example, 3 mm or 4 mm or a different thickness. The channel-like carrier, the carrier element and / or the holding element can be stamped parts, which are made by punching out of sheet metal of the desired thickness, or the parts can be produced by means of laser cutting, water jet cutting, a die-casting process, a 3-D printing process or in some other way be.

A luminaire comprises at least one first luminaire element. The lamp can basically be designed for various purposes, for example it can be designed for use as a pendant, hanging or wall lamp, as a built-in or surface-mounted lamp, floor lamp, lying light object or for other purposes. However, it can also comprise further lighting elements which, viewed in the longitudinal direction, can be joined together by means of holding elements at their ends. Using straight luminaire elements, for example, a long, straight luminaire can be constructed, using curvilinear luminaire elements or with luminaire elements whose opposite end faces are not parallel to one another, for example a curved, curved, circular, closed, oval, semicircular or wave-shaped luminaire can be constructed. It can also have a lampshade.

In addition to the lamp element described, a lamp can have at least one different type of lamp element which comprises at least one electrical component and is connected to the first lamp element by means of at least one holding element. The different type of lamp element can be a radiator element with at least one radiator that emits light in a directed manner, possibly also laser light. Alternatively or additionally, the different type of lighting element can also have other lighting means and / or other electrical components. Another electrical component of the different light element can be, for example, an electroacoustic element, for example a loudspeaker and / or a microphone, which can be relevant, for example, for voice control of the light or for monitoring or for announcements. The other electrical component can also comprise a camera and / or a sensor, for example a motion sensor or a proximity sensor. It can also include display elements and / or projection means and / or an energy store (battery, capacitor).

For example, the lamp can be a pendant lamp or a hanging lamp that is suspended from a room ceiling and can have at least one radiator element that preferably emits light downwards from the ceiling. Further shapes of the different type of lamp element are also conceivable, which include several radiators and emit light in several directions and / or have other lighting means. Different beam angles, in particular between 20 ° and 80 °, and light outputs, in particular 1000, 2000, 3000 or more lumens per radiator, and color temperatures, in particular between 2700 and 6000 Kelvin, are conceivable for the radiators, so that different lighting requirements are met depending on the application can. The illuminants can have tunable white illuminants. RGB lamps can be used, with which any light color can be generated.

Several luminaire elements of a luminaire can be arranged like a ring, so that a closed geometry results, the shape of which is determined by the design of the luminaire elements used. Different types of lamp elements, in particular spotlight elements, can be arranged between successive lamp elements as described above, the lamp elements and / or different lamp elements being connected by means of holding elements that are attached to the first and / or second end of each lamp element as required. The light sources can be mounted in the light elements in such a way that light is emitted in relation to the ring-like closed geometry of the light in the direction of the center of the ring and / or to the outside as well as upwards and downwards. The different types of lighting elements can be provided with spotlights that preferably emit light downwards. In this context, “ring-like” is to be understood as meaning that all luminaire elements of the same or different type result in a closed structure after being joined together. This structure can, for example, have the shape of a circular ring, but can also be rectangular, square, star-shaped or any other shape and does not have to be flat, but can also be shaped out of the plane of the ring.

For the different types of luminaire elements it is conceivable, provided they are shaped as emitter elements, that more than one emitter is attached per emitter element and / or that the emitter or emitters emit light in at least one direction other than downward. Luminaire elements can be put together alternately with luminaire elements of different types, or any sequence of luminaire elements of the same or different type can be used. It is also conceivable that more than two different types of luminaire elements are installed in a luminaire. Accordingly, a luminaire can be designed with any luminaire geometry and adapted to the space in which the luminaire is to be installed and operated.

The light sources installed in the luminaire can be switched together or separately in several groups or individually, can be changed in terms of light color and / or color temperature and / or can be dimmed. By specifically activating or deactivating different illuminants, different lighting moods can be specifically generated depending on the application, for example, depending on the situation, all illuminants whose light is directed downwards and / or upwards can be activated, while in another situation only spotlight elements or only the side light can be activated become. Any lighting scenarios can be created by individually controlling all the light sources installed in the luminaire.
